Abstract
We discuss the modifications of the e.m. polarizability and of the charge radius of a nucleon embedded in the nuclear medium. For a free nucleon these structure constants are influenced by the pion cloud. The distortion of this cloud by the nuclear environment produces an appreciable enhancement of the two constants. The implications for the deep inelasticee′ experiments is discussed.
